Figure 4.

Reductions in habitat extent and maximum population flow for 10 shorebird taxa, assuming upshore shifts of intertidal habitats. The loss of habitat extent (solid line) and loss of population flow (broken line) both rise with increasing sea levels, although the latter always equals or exceeds the former. Species vary in the degree to which the impact of habitat loss is magnified by migratory connectivity (the area between the two curves). Error bars indicate the highest and lowest range of losses in population flow from 1000 iterations.
